【问题描述】：

我未能在安卓上使用smack jabber。 app.gradle

实现“org.igniterealtime.smack:smack-android:4.3.1” 实现“org.igniterealtime.smack:smack-tcp:4.3.1”

Gradle 构建失败。

【问题讨论】：

你缺少implementation "org.igniterealtime.smack:smack-java7:4.3.1"依赖

添加没有效果。错误依然存在

在下面查看我的答案

谢谢，我已经发布了完整的 gradle 文件以获取完整的上下文。仍然显示错误

你试过关闭并重新打开android studio吗？类路径在这里应该不是问题...如果您评论 3 行 smack 实现一切正常吗？

【参考方案1】：

确保在您的项目build.gradle 中您拥有：

buildscript 
    repositories 
        google()
        jcenter()
        maven 
            url 'https://oss.sonatype.org/content/repositories/snapshots'
        
        mavenCentral()
    
    dependencies 
        classpath 'com.android.tools.build:gradle:3.2.1'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    


allprojects 
    repositories 
        google()
        jcenter()
        maven 
            url 'https://oss.sonatype.org/content/repositories/snapshots'
        
        mavenCentral()
    

在你的应用程序 build.gradle 的依赖块中：

dependencies 
   implementation "org.igniterealtime.smack:smack-java7:4.3.0"
   implementation "org.igniterealtime.smack:smack-android:4.3.0"
   implementation "org.igniterealtime.smack:smack-tcp:4.3.0"

configurations 
    all*.exclude group: 'xpp3', module: 'xpp3'

【讨论】：

谢谢，我不知道为什么，但它现在正在编译。奇怪

有时 Android Studio 仍然卡住并有奇怪的行为，当这种情况发生时，首先要做的就是重新启动它，看看是否能解决问题:)

这行似乎也是必需的。我把它漏掉了configurations all*.exclude group: 'xpp3', module: 'xpp3'

是的，正如文档所说，这行可能是必需的，我已经更新了完整的答案

smack 版本 4.3.1 也会触发错误。其他版本没有问题
